  • Optimisations for the single table region multiplication and carry less
    multiplication using NEON's polynomial multiplication of 8-bit values.
    
    The single polynomial multiplication is not that useful but vector
    version is for region multiplication.
    
    Selected time_tool.sh results for a 1.7GHz cortex-a9:
    Region Best (MB/s):   672.72   W-Method: 4 -m CARRY_FREE -
    Region Best (MB/s):   265.84   W-Method: 4 -m BYTWO_p -
    Region Best (MB/s):   329.41   W-Method: 4 -m TABLE -r DOUBLE -

  • Fix for coverity issue from Ceph project:
    
    CID 1193093 (#1 of 1): Structurally dead code (UNREACHABLE)
     unreachable: This code cannot be reached: "return gf_w4_double_table_i...".

  • Remove identical expression, reorganize code in gf_error_check()
    to be identical handled trough all checks. Removed (raltmap && arg1 != 4)
    check - this is dead code (arg1 is always 4 in this code path).
    
    Fix for coverity issue from Ceph project:
    
    CID 1193071 (#1 of 1): Same on both sides (CONSTANT_EXPRESSION_RESULT)
     pointless_expression: The expression (arg1 == 4 && arg2 == 32) ||
     (arg1 == 4 && arg2 == 32) does not accomplish anything because it
     evaluates to either of its identical operands, arg1 == 4 && arg2 == 32.
     Did you intend the operands to be different?
